stalled.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawing which forms a part of this specification and in which,

Fig. 1 is a side elevational view of a clock with a part broken away and embodying the invention which is shown in section.

Fig. 2 is a sectional View taken on line 22 of Fig. 1.

Fig. 3 is a fragmentary sectional view taken on line 3-3 of Fig. 2.

Fig. 4 is a view similar to Fig. 1 showing a slightly modified form of the invention.

As shown in the drawing, the shaft 8 on which the escapement wheel 9 is fixedly mounted is extended and the escapement wheel is enclosed in a sound-proof housing If]. The shaft H on which the detent yoke I2 is fixedly mounted is also enclosed in the housing Ill so that the entire equipment is enclosed in the sound-proof enclosure. In this way the ticking sound is entirely eliminated in a clock of this type. It will be noted that the housing I0 is mounted on the upper wall 3 of the clock works frame all of which are enclosed in the casing Hi.

In Fig. 4 I have elevated the frame to provide a yoke 15 in which the end of the shaft 8 is projected to form a bearing therefor. The end of the shaft II is also extended into the elevated portion I5 to provide a bearing, and the soundproof housing It is mounted so as to embrace the escapement movement.

In this way I have provided a clock action which is of the usual spring operated type and in which there has been a silencing of the ticking sound which usually emanates from clocks of this type. v

While I have illustrated and described the preferred form of construction, I do not Wish to limit myself to the precise details of structure shown but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a timepiece of the class described, a supporting frame embodying a. pair of oppositely disposed plates; means for securing said plates together in spaced relation; a clock mechanism 15 mounted on said frame between said plates; a sound-proof housing positioned on said frame with one of the sides of said housing engaging the outer face of one of said plates; means for securing said housing in fixed relation to said 2 plates; a pair of shafts journalled in said frame and projecting through the plate engaged by said housing and extending into said housing; an escapement wheel fixedly mounted on one of said shafts in said housing; a pinion mounted on 25 said last-named shaft between said plates and cooperating with said clock mechanism for rotating said last-named shaft; and a detent mounted on the other of said shafts within said housing for cooperating with said escapement wheel. 3

2. In a timepiece of the class described, a supporting frame embodying a pair of oppositely disposed plates; a clock mechanism mounted on said frame between said plates; a sound-proof housing positioned on said frame with one of 35 the sides of said housing engaging the outer face of one of said plates; means projecting through said plates and through said housing for securing said plates together and securing said housing thereon in fixed relation thereto; a pair of shafts journalled in said frame and projecting through the plate engaged by said housing and extending into and terminating in said housing; an escapement wheel fixedly mounted on one of said shafts in said housing; a pinion mounted on said last-named shaft between said plates and cooperating with said clock mechanism for rotating said last-named shaft; and a detent mounted on the other of said shafts within said housing for cooperating With said escapement wheel.
